User's preference applied feeling-based image color control method using interactive genetic algorithm

Abstract

A method is provided that controls the color of a feeling-based image reflecting a user's preference via an interactive genetic algorithm. The method is performed in such a manner that a range of candidate colors is defined by type of feelings as templates, one from among the candidate templates, as the final template, is selected by learning a user's color preference via an interactive genetic algorithm, and then the color of an image is controlled based on the final template by recognizing a user's feeling.

1 . A method for controlling the color of a feeling-based image, comprising:
 (1) defining a range of candidate colors by type of feelings as templates;   (2) selecting one from among the candidate templates, as the final template, by learning a user's color preference via an interactive genetic algorithm; and   (3) controlling the color of an image based on the final template by recognizing a user's feeling.   
     
     
         2 . The method of  claim 1 , wherein the defining of the range of candidate colors comprises:
 analyzing a relationship between color and feeling to determine a range of color reflecting respective feelings; and   defining the analyzed result as templates representing a range of colors corresponding to the respective feelings,
 wherein the defined templates form a number of candidate templates to reflect the variety of relationship between color and feeling. 
   
     
     
         3 . The method of  claim 2 , wherein each of the candidate templates comprises:
 seven hue templates, four saturation templates, and four brightness templates.   
     
     
         4 . The method of  claim 1 , wherein the selecting of one from among the candidate templates comprises:
 creating an initial individual by selecting one of the defined templates, controlling the color of an image by applying the initial individual thereto, and displaying the color controlled image;   receiving a user's estimated value regarding the displayed color controlled image via a user interface, and selecting an individual to hand over to the next generation by selecting a tournament according to the user's level of image satisfactions and by using an elitism;   computing a one point cross with respect to a parent individual, and creating a variation by changing a bit; and   determining a combination of hue, saturation, and brightness templates for the final individual reflecting a user's preference.   
     
     
         5 . The method of  claim 1 , wherein the controlling of the color of an image comprises:
 controlling saturation and brightness by a gamma correction of an exponential transformation function as a nonlinearity function.
